A personal monitor for monitoring a biomedical condition, such as a heart rate. A sensor provides a signal related to the biomedical condition and the signal is encoded for repeated wireless transmission to a receiver. An encoded identification signal is also repeatedly sent to the receiver to identify the transmitter to the receiver in order to prevent the adverse effects of Interference which occurs if signals other than those from the transmitter are received. The monitor detects deviations (errors) from an expected pattern and recovers from these deviations (error correction) to display an accurate value of the biomedical condition. If too many errors are present due to interference, faulty transmission and/or reception, etc., the frequency over which wireless transmission occurs can be changed. In one embodiment, the value of the biomedical condition is wirelessly sent to the receiver. In another embodiment, the value of the biomedical condition is determined in the receiver based on the encoded signal that is received. The receiver rejects all signals that are not from the transmitter.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

Turning now descriptively to the drawings, in which similar reference characters denote similar elements throughout the several views, FIGS. 1 through 10 illustrate the combination vehicle alarm and locator system of the present invention indicated generally by the numeral 10.

A pictorial view of the use of the vehicle security feature of the combination vehicle alarm and locator system 10 is illustrated in FIG. 1. As can be seen from this Figure, the user 12 is standing outside a vehicle 14 with the control unit 20 of the combination vehicle alarm and locator system 10. The combination vehicle alarm and locator system 10 also functions as a locator device. Positioned on the control unit 20 is a first key 22 for activating the vehicle security functions of the combination vehicle alarm and locator system 10. When the first key 22 is activated, the control unit 20 generates and transmits a signal to the vehicle 14. The signal is indicated by the line labeled with the numeral 16. The signal 16 is received by the security system of the vehicle 14 and acts to either activate or deactivate the security system. The vehicle security system preferably generates an audible signal when either the system is activated or an attempt is made to circumvent the system. The audible signal generated by the security system is represented by the arced lines labeled with the numeral 18.

FIG. 2 illustrates the combination vehicle alarm and locator system 10 being used by a person 12 lost in a wooded area 24. The person 12 is shown with the combination vehicle alarm and locator system 10 in hand and utilizing the locator function of the system 10 to obtain assistance in finding his way. Also shown is another person 26 attempting to find his way using a map 28. This view illustrates the contrast between use of conventional methods for finding ones way and the use of the combination vehicle alarm and locator system 10 of the present invention. The combination vehicle alarm and locator system 10 is constantly generating and transmitting a location signal indicated by the arced lines labeled with the numeral 30. The location signal 30 is a wave pattern transmitted by the combination vehicle alarm and locator system 10 to an orbiting satellite of the Global Positioning Satellite System which in turn transmits a signal indicating the location of the user and identification information concerning the user to an operations station as can be seen in FIG. 3. The operations station is thus able to determine the position of the control unit 20 and thus the person 12 in possession of the control unit 20 at any time. Upon activation of a second key 32 of the control unit 20, an alarm signal is generated and transmitted along with the location signal 30. This alarm signal alerts the operations station that the person 12 is in need of assistance. Upon receipt of the signal, the operations station dispatches assistance to the user 12 at the identified location. As the location signal 30 indicating the location of the control unit 20 is constantly transmitted and received by the operations station, the operations station can locate the control unit 20 at any time irrespective of whether the second key 32 was activated.

A pictorial view illustrating the operation of the combination vehicle alarm and locator system 10 within a locating system is shown in FIG. 3. This figure shows the transmitting and receiving relations between the combination vehicle alarm and locator system 10 held by the user 12, an orbiting satellite 31 and an operation station 32 when utilizing the locator function. A plurality of operation stations 32 are positioned throughout the world and indicated by the black points. The control unit 20 is constantly transmitting a location signal to the orbiting satellites 31 of the G.P.S, system which receive the signal and determine the location of the control unit 20. The orbiting satellite 31 then transmits a location signal to the operations station 29, thereby allowing the operations station 29 to locate the control unit 20 at any time. When a user 12 is lost or injured at a particular location and requires assistance, the user 12 activates the second key 32 on the control unit 20. Upon activation of the second key 32, an alarm signal is generated and transmitted along with a constantly transmitted location signal 30 as indicated by the arced lines labeled with the numeral 28. The signal 28 is transmitted to a satellite 31 of the G.P.S. locator system. The signal transmission from the control unit 20 to the satellite 31 is indicated by the arrow labeled with the numeral 34. The satellite 31 receives the signal and determines the location of the control unit 20 transmitting the signal. Upon determining the location of the control unit 20, the satellite 31 transmits a signal including the location and identification information concerning the activated control unit 20 to operation stations 32 strategically located around the earth 38. The signal transmitted by the satellite 31 is indicated by the arrow labeled with the numeral 36. Upon receipt of the location signal, the operation stations 32 are able to determine if they are located near the user 12 and provide assistance to the user.

A perspective view of a lost child 33 having the combination vehicle alarm and locator system of the present invention is illustrated in FIG. 4. As can be seen from this figure, the lost child 33 is carrying the control unit 20 within a pocket 35 of an item of clothing 37. When an adult is worried that their child is lost or in trouble, all that need be done is to contact the operations station as shown in FIG. 5. As the control unit 20 constantly transmits a location signal 30 to the operations station via the G.P.S. satellite system, the operations station is able to constantly monitor the location of the control unit 20 and thus the child carrying the control unit 20.

A pictorial view illustrating the operation of the combination vehicle alarm and locator system 10 for locating a child 33 is shown in FIG. 5. As can be seen from this figure, a parent 39 is worried as to the location of a child 33. When the parent 39 is worried, the parent 39 is able to call the operations station 29 to determine the location of the child 33. The child 33 is carrying the control unit 20. The control unit 20 constantly transmits a location signal 30 to the operations station 29 via a G.P.S. satellite 31. The G.P.S. satellite 31 receives the signal 30 determines the location of the control unit 20. The G.P.S. satellite 31 then transmits a signal 36 to the operations station 29. The signal 36 includes the location of the control unit 20. This signal 36 is received by a receiver dish 41 at the operations station 29 and provided to a computer system 45. When the parent 39 contacts an operator 43 at the operations station 29, the operator 43 is able to relay the location of the child instantaneously as the operations station 29 constantly monitors the location of the control unit 20 and provides the location information to the central computer system 45.

An enlarged perspective view of the control unit 20 is shown in FIG. 6. As can be seen from this figure, the control unit 20 includes a housing 42. Extending through a face side 44 of the housing is the second key 32 and a visual indicator 48. A cover 50 provides selective access to the second key 32 thereby decreasing the possibility of accidental activation of the locator function of the combination vehicle alarm and locator system 10. Activation of the second key 32 causes the alarm signal to be generated and transmitted to the G.P.S. satellite 31 along with the location signal 30. Also extending through the face side 44 of the housing 42 is the first key 22 for activating of the vehicle alarm system. The first key 22 includes a first button 25 for activating the vehicle security system and a second button 27 for deactivating the vehicle security system. The visual indicator 48 includes a first LED 52 for indicating that the battery is low, a second LED 54 for indicating that the device is operating properly and a third LED 56 for indicating that the second key 32 has been activated. Activation of the second key 32 causes the third LED 56 to illuminate as indicated by the dotted lines labeled with the numeral 58. The third LED 56 may be made to flash and thereby provide a more visible indication that the second key 32 has been activated. The first LED 52 illuminates similarly to the third LED 56 when the battery power is low and the second LED 54 illuminates when the device is properly operating. Positioned on a side of the housing 42 is an antenna 58 through which the signal is transmitted to the G.P.S. satellite 31. A key ring 60 is connected to an end of the housing 42 by a key ring retainer 62. The key ring retainer 62 is releasably connected to the side of the housing 42 and therefore is optionally removable from the control unit 20. A battery 64 is slidably positioned into a recess in the housing 42. A cover 66 for covering infrared LED's for transmitting a signal upon activation of the first key 22 is provided on a side of the housing 42.

A view of the back side of the combination vehicle alarm and locator system 10 is shown in FIG. 7. As can be seen from this view, positioned on a back side of the control unit 20 is a clip 70 for attaching the control unit 20 to an article of clothing or accessory of the user. The clip 70 aids the user in retaining the control unit 20 in a non-obtrusive manner. Also positioned on the back side 68 is a speaker 72 through which audible signals may be generated. The generation of audile signals may optionally occur upon activation of the second key 32 and is illustrated by arced lines labeled with the numeral 73. The audible signals are preferably in the form of a screeching sound for the purpose of frightening away attackers. Extending from a side of the housing is the removable key ring retainer 62 and key ring 60. The removable key ring retainer 62 is selectively removable from its position connected to the control unit 20. Extending from another side of the housing is the antenna 58.

A cross-sectional view of the control unit 20 of the combination vehicle alarm and locator system 10 is shown in FIG. 8. As can be seen from this view, the housing 42 includes a top section 74 and a bottom section 76. Positioned between the top and bottom sections 74 and 76 is the internal circuitry 78 of the first key 22 for vehicle security system 10. The top section 74 includes a first recess 80 through which the second key 32 extends, second recesses 82 for receiving the visual indicators 48 and a third recess for receiving the first key 22 for the vehicle security system. Selectively extending from a side of the housing between the top section 74 and the bottom section 76 is the key ring holder 62. The key ring 60 is connected to the key ring holder 62. On a side of the housing 48 opposite the key ring holder 62 is the cover 66. Positioned within the housing and aligned with the cover 66 is an infrared LED 86 for transmitting an infrared signal to a vehicle upon activation of the first key 22. Positioned on the bottom section 76 of the housing 42 is a clip retainer 86. The clip retainer 88 releasably secures the clip 70 to the bottom section 76. Positioned on the bottom side but not shown in this figure is the speaker for generating the audible signal upon activation of the first key 22 or the second key 32.

FIG. 9 shows a schematic diagram of the control unit 20 of the combination vehicle alarm and locator system 10. As can be seen from the figure, the control unit includes a first location section 88 and a second vehicle security section 90. Within the first section 88 is a processor 92. The processor 92 is connected to the power source 64. The power source 64 is monitored by a sensor 94 which determines the power level of the power source 64. Upon determining that the power level is below a threshold value, the sensor 94 will activate the low power level LED 52 of the visual indicator 48. A memory 96 is connected to the processor 64 for storing identification information concerning the control unit 20 to be transmitted upon activation of the second key 32. The operation LED 54 and the alert LED 56 are also connected to the processor 92. The second key 32 is also connected to the processor 92. A transmitter 98 is connected between the processor 92 and the antenna 58 for transmitting a signal including the identification information concerning the control unit 20 upon activation of the second key 32.

The second section 90 is provided for activating and deactivating a vehicle alarm system, The second section 90 includes a processor 100 positioned therein, The processor 100 is connected to the power source 64. Alternatively, the second section 90 may include another power source. Connected to the processor 100 are the alarm activate button 25 and the alarm deactivate button 27. A transmitter 102 is also connected to the processor 100. The transmitter 102 is preferably an infrared LED for generating and transmitting an infrared signal to the vehicle alarm system.

The operation of the combination vehicle alarm and locator system 10 will now be described with reference to the figures. In operation, the combination vehicle alarm and locator system 10 is able to both activate a vehicle alarm system and also transmit a distress call through the Global Positioning Satellite System to provide an operations center 29 with a location of a user retaining the control unit 20 of the combination vehicle alarm and locator system 10. In this manner, the operations center 29 is able to dispatch assistance to the user of the combination vehicle alarm and locator system 10. In operation, the control unit 20 of the combination vehicle alarm and locator system 10 is to be retained by the user for activating a vehicle alarm system, deactivating the vehicle alarm system and transmitting a signal to the Global Positioning Satellite System for use in obtaining assistance when injured or lost. The combination vehicle alarm and locator system 10 acts similarly to a conventional vehicle alarm control when the first key 22 for activating a vehicle alarm are utilized.

The combination vehicle alarm and locator system 10 also includes the locator function. The operation of the locator function is described in FIG. 10, As can bee seen from this figure, This function is beneficial when the user suffers an injury or is lost as discussed in step S2. Upon determining that the user is lost or injured, the user activates the second key 32 as stated in step S4. Upon activation of the second key 32, the transmitter 92 retrieves the identification information stored in memory 96 as described in step S6. The processor 92 then optionally activates the speaker 64 to generate an audible signal which may be heard by persons in the area of the user as discussed in step S8. The processor 92 also activates the transmitter 98 to transmit a signal including the identification information and an alarm indication to a G.P.S. satellite as stated in step S10. The signal is received by the G.P.S. satellite 31 as described in step S12. The satellite 31 receives and analyzes the data for generation of a location signal as discussed in step S14. The satellite 31 then transmits the location signal and the identification information to an operations station 29 as stated in step S16. The operations station 29 receives the signal from the satellite 31 and analyzes the signal to determine the location and identification of the user as described in step S18. Upon determining the location and identification of the user, the operations station 29 contacts the authorities in a location near the user so that the authorities may aid the user as stated in step S20.

The user is thus able to contact assistance when needed and also activate a vehicle alarm system using a single handheld control unit 20. The control unit 20 also may be used to retain keys thereon. The control unit 20 may also be clipped to an article of clothing worn by the user using the clip 70 on the back side and thus is unobtrusive to the user.

From the above description it can be seen that the combination vehicle alarm and locator system of the present invention is able to overcome the shortcomings of prior art devices by providing a combination vehicle alarm and locator system which is able to utilize the Global Positioning Satellite (G.P.S.) system and includes a selectively actuated vehicle security function. The combination vehicle alarm and locator system is also able to optionally generate an audible tone, is small, light weight and includes a key ring selectively attached thereto. The combination vehicle alarm and locator system able to provide an alternative to dialing 911 in the case of an emergency when a phone is not available. Furthermore, the combination vehicle alarm and locator system of the present invention is simple and easy to use and economical in cost to manufacture.
